Abstract (en)
A control device of an aerosol inhaler includes a load 21 heating an aerosol generation source, in which a temperature and an electric resistance value of the load are correlated. The control device includes: a voltage sensor 17 configured to output a voltage value applied to the load; a constant current circuit configured to output a constant current to the load; and a control circuit 50 configured to acquire the electric resistance value of the load or the temperature of the load based on output of the voltage sensor and the constant current.
